Supermoon this Sat. Beginners who like to shoot full moon, get ready.

Sorry Josh, while your theory is reasonable, Canon disagrees with you. In the Canon EF70-200mm f/4L IS USM lens manual, page 10, section 8, it states "To compensate for shifting of the infinity focus point that results from changes in temperature". Same verbiage for my 24-105mm f.4 L IS USM lens, page 8, section 5. In both manuals, the next sections deal with the infrared marks.

......... Many lenses have their "infinity" stop beyond the infinity point, to allow for expansion and contraction of the lens due to temperature.

And all these years I thought is was because infrared has a different focus point than visible light.

I don't think it has anything at all to do with temperature. And it's not IR either. IR focus is on the near side of infinity, not the far side (look at your lenses if you don't believe me).

My theory is that the over-travel allows the AF mechanism to overshoot it a little, then come back. (To avoid damage from the lens slamming into infinity.)


Just a couple observations - every AF lens I have used will go past infinity. Every MF lens I have used has a hard stop at infinity.


edit
In case anybody is wondering about the different focus point for IR - that's what the red dot is for. When you're shooting IR, use the red dot instead of the line.
And if that still doesn't make any sense to you, you probably don't have any lenses that have distance scales on them.

I recall my 35mm film camera lenses saying in the instructions that's the reason the lens goes past infinity. And none of them were AF.

Damn.. It's raining.. and very cloudy! NO MOON!

 

[pgriz]

Managed to get a few. We've got a high-pressure system over us and this has given us clear skies.

For this series, I decided to go to the waterfront and try to catch the moon rising over two of our bridges connecting the Island of Montreal to the south shore of the St-Lawrence. In retrospect, not the most scenic of views, but until you try, you just don't know what you will get.

Here is my first attempt at shooting the moon Unfortunately I forgot all about the moon until about 10pm - I wanted to catch it rising.

Here is one I got. Forgot about the moon till I saw it peeking through the clouds and thought I would grab the camera. My bonehead didn't think to grab the tripod though .

I'm in the same boat... Really sucks as I was looking forward to it

Is the first shot Le Pont Champlain?

Did you get any du Pont Jaques Cartier?

 

[pgriz]

No, that was the railway bridge between Lasalle and Kagnawaga, with the Mercier bridge behind it. I was in Parc Réné Levesque, which is at the west end of Lachine Canal. I was thinking that Jacques Cartier would be more interesting, but couldn't find a good vantage point given where the moon was going to rise.

My first attempt at shooting the moon.
Honestly, it didn't seem that "super" to me at all and I had to really focus in since it wasn't that large compared to the horizon.

Ah well, it's a learning experience.
I shot it manual with a high ISO and f16.

 

[RxForB3]

Well I managed an attempt. Unfortunately it was with my new-to-me Sigma 50-500mm. I say unfortunately because it didn't come with the tripod collar and was WAY too heavy for my tripod. So I had to handheld by propping myself on the car roof. Here is the result, in any case...what do you think for my first attempt at the moon?

Here is my attempt:

 

[bernesoftware]

Hi to all... I sure was excited shooting the Super Moon... with my D90. Sure enough, never done it before. So I hit the web, forums, wiki... and most recomendations in between.
So even after almost 30 shots with different settings, I can not get passed the fuzzy white ball. No features... and defffinitly overexposed look. Here is range os settings I have tried:
Manual
Focus to infinity
F/16 or 11 or 8 (some 5.6)
ISO 1 or 200, 400
Shutter 1/125, 250-400
Pause 10 sec.
Menu/Custome Setting Menu/ (d)(Shooting/display)/ (d10) Exposure delay mode/on
Meetring 10

Please help.
